Diagnosis: This species can be recognized by a ventroapical keel on the hind trochanter ( Fig. 145B View FIGURE 145 ); elongated surstyli, left surstylus club-shaped, right one with a triangular lobes ventroapically in dorsal view ( Fig. 95A View FIGURE 95 ); gonopods elongated, left little longer and wider than right one with a distinct projection on inner margin ( Fig. 95B View FIGURE 95 ); phallic guide with 3–4 short dorsolateral spines in ventral view.

Description: MALE: Body length: 2.5 mm. Head. Flagellum acuminate; yellow-brown, scape and pedicel dark brown. Face silvery pollinose. Frons, upper part shining black; lower part distinctly silver pollinose; eyes touching for distance equal to 2 times the length of ocellar triangle. Occiput silvery pollinose, less so on upper 1/3. Thorax. Postpronotum pale, with 3–4 dark bristles. Mesonotum (viewed obliquely from front) silvery brown pollinose. Dorsocentral bristles short, numerous dark bristles around postpronotum present. Scutellum silvery brown pollinose and with 4–6 scattered bristles. Halter, stem and knob pale, tip brownish, base brown. Legs. Mid coxa with 3–4 long dark bristles. Trochanters brown, femora black, shining ventrally, silvery pollinose posteriorly except shiny hind femur; knees and basal 1/6 of tibiae yellow (tibiae otherwise brown), tarsal segments bright yellow completely. Hind trochanter with a keel ventroapically; 1–2 ventrobasal short bristles present on fore mid femur. Hind femur without ventroapical spines, except 8–10 equally spaced short bristles posteroventrally, longer on distal half, longest up to 1/3 the width of hind tibia at distal end. Short subapical spines on fore- and mid tibiae present. Hind tarsomeres distinctly flattened, hind metatarsus almost as long as 2–4 combined, all tarsomeres with erect bristles dorsally. Pulvilli shorter than last tarsal segment. Wing. Length: 2.5 mm. Upper side of basal costal cell with one short dark brown bristle. Fourth costal section 3 times as long as third costal section. Cross-vein r-m at middle of discal cell. 2–3 short dark setulae on tegula. Abdomen. Viewed obliquely from front tergites subshiny brown, tergite 1 silvery brown grey pollinose. Dispersed short dark bristles on all tergites present. Lateral bristles on first tergite present, 6–8 dark bristles up to as long as hind femur’s width at base. Genitalia. Genital capsule in dorsal view: epandrium longer than wide (MLE:MWE = 1.5). Surstyli elongate, left surstylus broadened on apical half, apex club-shaped; right one with a triangular lobes ventroapically, left surstylus is longer than right one ( Fig. 95A View FIGURE 95 ). Genital capsule in ventral view: gonopods unequal, left is little longer and wider than right one, elongated towards surstyli, both gonopods with a distinct projection on inner margin; phallic guide with 3–4 short dorso- dorsolateral spines; subepandrial sclerite long ( Fig. 95B View FIGURE 95 ); Genital capsule in lateral view: both surstyli curved towards sternite, rather widened at basal half, narrowed at apical half ( Fig. 95D–E View FIGURE 95 ). Ejaculatory apodeme tube-like, bent, with a bulb in its middle ( Fig. 95C View FIGURE 95 ).
